Abstract

Des systèmes de biocapteurs comprennent un dispositif de mesure et des capteurs dessai comportant au moins trois électrodes indépendamment adressables, au moins deux de ces électrodes étant essentiellement isolées chimiquement. Une ou plusieurs électrodes de travail peuvent être combinées à deux contre-électrodes ou plus. Les deux contre-électrodes ou plus peuvent fonctionner à des potentiels différents pour fournir une analyse électrochimique multianalyte. Des procédés danalyse sont fournis pour effectuer une analyse électrochimique multianalyte et des capteurs dessai présentant une résistance au mélange chimique entre des régions danalyse secondaires.
